A groundbreaking study has just come out that used various MRI techniques to map the structure and function of human brains. We are working with MRI experts to do similar things with the heart. Here’s a figure from the paper illustrating the process:

The study was done by an international team of scientists, with first author […]

This study asked an interesting question: “Is it safe for a rescuer to continue chest compressions during defibrillation of a rescuee?”
You’d think that with the high voltages involved, and mental images of TV doctors yelling “CLEAR!” before defibrillating, there’s no way it could be safe. Apparently, for a gloved rescuer, even with a “worst-case” […]

Simulations of real systems make it possible to test “what if” questions, and compare the results with what did happen. For example, I am working on a study in which a stimulus pulse turns on and off while a spiral wave rotates about an obstacle. We can ask, “What happened to the spiral wave following […]

We do a lot of really cool and scientifically interesting stuff in both our lab and the field as a whole. We have now developed our technology to the point where we can take an MRI scan of a heart and develop a complete model, with accurate fiber directions from diffusion tensor data, in a […]

In this article, a boy was struck by lightning at lacrosse camp, given CPR and defibrillated three times with an AED, and eventually made a full recovery.
Amazing. AEDs continue to come down in price, and are really racking up an extensive list of saved lives.
